Featuring Advanced Series Mode technology and Impedance Tolerant EMI/RFI filtration, they provide patented surge elimination and conditioning for equipment that relies on peak AV performance. Unlike common protection solutions, the Standalone's patented technology is comprised of non-sacrificial components that never degrade or fail, guaranteeing equipment stays protected. They eliminate surge energy up to 6,000 Volts without producing harmful ground contamination or common mode disturbances that can cause hissing sounds and pixilation on AV systems to ensure pristine sound and video.
